We do so using several effective models in order to reliably capture the relevant non-perturbative dynamics. This approach allows us to explicitly calculate key quantities characterizing the $\\chi$PT without having to resort to rough estimates. Most importantly, we find that the transition's inverse duration $\\beta$ normalized to the Hubble parameter $H$ is at least two orders of magnitude larger than typically assumed in comparable scenarios, namely","authors_text":"Alexander J.
